openSUSE 11.4 going to sleep

How's it going everyone. I'm not sure if this will be a dupe request but i tried to search for it all over the place. The issue i'm having is openSUSE going to sleep. It causing problems with keeping my server active and i can't find the right direction to resolve it. I went through the perfect server for openSUSE 11.4 and ISP config 3, which works like a charm i might add but everytime my server goes to sleep, everything is inaccessable. Any help will be greatly appreciated. i tried this

YaST / System / System Service (Runlevel) / Select Expert Mode / Select Service pm-profiler then select the bottom right button Set/Reset and Enable the Service and OK to any questions. Now select the bottom left button Start/Stop/Refresh and select Start Now. Then Pick OK in bottom right to make your selections permanent.
